Subject: [PATCH] mac80211: never drop injected frames even if normally not allowed
Git-commit: 1df2bdba528b5a7a30f1b107b6924aa79af5e00e
Patch-mainline: v5.9-rc1
References: jsc#SLE-13430

In ieee80211_tx_dequeue there is a check to see if the dequeued frame
is allowed in the current state. Injected frames that are normally
not allowed are being be dropped here. Fix this by checking if a
frame was injected and if so always allowing it.
